Judgments of duration, figure - Ground contrast, and size for words and nonwords

Abstract

Does the word-superiority effect on letter discrimination result in a word-superiority effect on duration judgments? We examined this question in five experiments. In the first four experiments, we have demonstrated that (1) words shown for 32-80 msec were judged as presented longer than nonwords shown for the same duration; (2) this word-superiority effect persists if the stimuli are shown for an objective duration of up to 250 msec; and (3) these effects can be extended to judgments of figure-ground contrast and letter size. These findings extend existing data on effects of processing fluency on perceptual judgments, hi Experiment 5, we found that duration judgments were higher for words than for pronounceable nonwords, and duration judgments were higher for pronounceable nonwords than for nonpronounceable nonwords. We discuss the implications of this finding for the discrepancy-attribution hypothesis (Whittlesea & Williams, 1998, 2000, 2001). Copyright 2004 Psychonomic Society, Inc.
